As the colouring agent of dyed layer, can enumerate pigment or dyestuff.The colouring agent of dyed layer is used the various colouring agents that using in all the time making the painted purposes of cosmetic sheet.Concrete example about preferred colouring agent, can enumerate the phytochromes such as (1) indigo, alizarin, carthamin, anthocyanin, flavonoids, alcannin, (2) food colorings such as azo, xanthene, triphenyl methane, (3) natural inorganic pigment such as loess, terre verte, (4) organic pigment such as acrylic acid series, carbamate system, (5) calcium carbonate, titanium oxide, aluminium color lake, madder lake, alkermes color lake etc.
In order to form dyed layer, can use by the metallic film fragment being dispersed in adhesive resin and the black liquid with mirror-like metallic luster obtained (hereinafter referred to as highlighted property China ink liquid.) the highlighted property China ink liquid layer that forms.The metallic film fragment is the scope of 3～60 quality % with respect to the content of the nonvolatile component in black liquid.Use the highlighted property China ink liquid of metallic film fragment as pigment, the metallic film fragment is parallel-oriented with respect to the coated article surface in printing or while being coated with this China ink liquid, and its result obtains the mirror-like metallic luster of high brightness.
In addition, patterned layer means the layer of word or style.About composition and the formation method of patterned layer, except form with pattern graph of a correspondence shape, all the same with dyed layer.
In addition, adhesive linkage is formed in the inner surface of transfer sheet and wants the part bonding with decorated article.That is, in the situation that want, make inner surface whole bonding with decorated article, form adhesive linkage on its whole surface.In addition, in the situation that want, make the part of inner surface and decorated article bonding, a part therein forms adhesive linkage.
As the constituent material of adhesive linkage, as long as can access the cementability enough with decorated article, be not particularly limited.In the situation that the adhesive linkage heating is crimped on decorated article, as the constituent material of adhesive linkage, suitably select the synthetic resin of thermal sensitivity, pressure-sensitive to get final product.
For example, in the situation that the constituent material of the surface portion of decorated article is polyacrylic resins, as the constituent material of adhesive linkage, preferably use the polyacrylic resin.In addition, for example, in the situation that the constituent material of the surface portion of decorated article is polyphenylene ether copolymer, polystyrenic copolymer resin, polycarbonate-based resin, phenylethylene resin series, polystyrene hybrid resin, as the constituent material of adhesive linkage, suitably polyacrylic resin, polystyrene resin, polyamide-based resin etc. with compatibility of choice for use and these resins get final product.
And then, for example, in the situation that the constituent material of the surface portion of decorated article is acrylic resins, as the constituent material of adhesive linkage, can use chlorinated polyolefin resin, ethlyene dichloride-vinyl acetate copolymer resin, thermoprene, coumarone-indene resin.
The thickness of adhesive linkage is preferably 0.5 μ m～50 μ m.At the thickness of adhesive linkage, be 0.5 μ m when above, can obtain enough cementabilities easier and infalliblely.At the thickness of adhesive linkage, be 50 μ m when following, easily dry after transfer sheet is fixed in to decorated article, so preferably.
With regard to the formation of each resin bed in the layer that forms transfer printing layer, unless otherwise specified, just can utilize with in the past the same method and carry out.In the example of in the past layer formation method, the coating process such as gravure coating method, rolling method, spot printing method of the black liquid that used the composition that contains constituting layer or coating are arranged, the print processes such as woodburytype, silk screen print method.
Stripping film
Forming the substrate 3 of stripping film 1, is sheet material or the membrane material all the time used in supporting the purposes of patterned layer, hard conating with sheet.Membrane material refers to the sheet material formed by synthetic resin.As synthetic resin, preferred resin can enumerate from polycarbonate-based resin, polyamide-based resin, polyimides be resin, polyester based resin, acrylic resin, olefin-based resin, carbamate be resin, and acronitrile-butadiene-styrene be at least a synthetic resin of selecting resin.
In addition, as substrate, can enumerate the single-layer sheet that formed by above-mentioned synthetic resin, (material of each single-layer sheet forms by the stacked laminates obtained more than 2 layers of single-layer sheet, the synthetic resin select from above-mentioned group as long as use, can be identical or different), used the copolymerization sheet material of above-mentioned synthetic resin etc.
The thickness of substrate is preferably 5～500 μ m.When the thickness of substrate is that 5 μ m are when above, in the situation that transfer sheet is fixed in to decorated article, the handling property (handling) in the time of can further fully guaranteeing to be configured in transfer sheet on mould.In addition, when the thickness of substrate is 500 μ m when following, appropriate rigidity can be obtained, handling property can be further fully guaranteed.
Delustring layer 4 be the outermost surface of transfer printing layer is configured as to the delustring shape and decorative article is given delustring outward appearance the layer.Delustring layer 4 is peeled off from transfer printing layer together with substrate 3 when transfer printing.By the part on the face of substrate, form delustring layer 4, can combine the performance on glossy surface and delustring (tarnish) surface.
As delustring layer 4, use alkyd amino be resin, urea melamine series resin and with their mixture as principal component and contain silica or carbon black gets final product as the material of delustering agent.
Be used to form delustring China ink liquid or the antiglossing pigment of delustring layer 4, preferably use contain organic solvent, as the heat-curing resin of bond and as the silicon oxide particle of delustering agent or the composition of carbon black particle.As the example of heat-curing resin, can enumerate the resin combination that has coordinated resin 5～40 % by weight that make the amino non-drying oil acid modified alcoholic of having of urea, melamine, guanamines, aniline and so on and formaldehyde carry out addition condensation and obtain; Or the mixture that makes melamine and urea reacts with formaldehyde generation cocondensation and resin of the mixture of the resin, epoxy resin and the melmac that obtain etc.
As the silica of delustering agent or the particle of carbon black, average grain diameter is 0.01～50 μ m, preferably 0.1～20 μ m, more preferably 1～15 μ m.When the average grain diameter of delustering agent is less than 0.01 μ m, diminish the decoration of good delustring style, while surpassing 50 μ m, the delustring particle is excessive and diminish the printing adaptability of black liquid.
Silicon oxide particle is used and gets final product such as the particle obtained from quartz or silicic acid anhydride etc., and carbon black particle is used for example by the thermal decomposition of natural gas, oil, creosote wet goods hydrocarbon and the particle that unburnt combination obtains.
About delustering agent, in delustring China ink liquid or antiglossing pigment, typically take solid constituent as its content of benchmark as 0.5～20 % by weight, preferably 1～10 % by weight, more preferably 3～8 % by weight.When the content of delustering agent is very few, can not obtain the decoration of good delustring style, in the time of too much, delustering agent precipitates, condenses in black liquid, can cause harmful effect to the printing adaptability.
For delustring layer 4 is set on the face at substrate 3, use the common print processes such as offset printing method, woodburytype, silk screen print method to get final product.In order effectively to form high-quality figure, wherein preferably use woodburytype.
But, in the situation that delustring China ink liquid or antiglossing pigment contain above-mentioned alkyd amino, be resin or urea melamine series resin, they are heat-curing resins, the printing adaptability of this China ink liquid or coating is deteriorated.For example, in the situation that carry out intaglio printing, heat-curing resin is attached on whole version thinly along with the increase of printing number.Therefore, be difficult to remove fully with scraper will adhere on the protuberance of version unnecessary black liquid.Its result, have black liquid residual at the protuberance of version, and the gloss of substrate zone can produce scum as mentioned above.
The thickness of delustring layer 4 is 0.1 μ m～50 μ m.If be less than 0.1 μ m, while when transfer printing becomes two dimension, 3D shape or is being shaped, carrying out transfer printing, substrate 3 is stretched, and the delustring layer likely is sheared because of this part, likely loses the delustring sense.In addition, when surpassing 50 μ m, while when transfer printing becomes two dimension, 3D shape or is being shaped, carrying out transfer printing, can't follow the stretching, extension of substrate and self crack at the delustring layer.More preferably the thickness of delustring layer is 0.5～30 μ m, further preferred 1～20 μ m.
Release layer 5 is to give the release property for transfer printing layer, the layer of the scum of coating simultaneously to the whole release surface of stripping film.Fig. 5 means the sectional view that has formed the state after the release layer in the gloss zone of Fig. 4.Release layer 5 coating scums 41, by the concavo-convex planarization of surface texture.
In the situation that carry out woodburytype, after version has been coated with to black liquid, rub with scraper.Therefore, even if having black liquid residual also for a small amount of at the protuberance of version, the amount of the delustering agent particle contained in residual black liquid is considerably less.Its result, on the face of substrate 3, the scum 41 that forms of the part in gloss zone 31, compare the concavo-convex quite little of surface texture with delustring layer 4.Therefore, form the suitable release layer 5 of thickness by the whole release surface at stripping film, can be in the situation that the surface texture of residual delustring layer 4 concavo-convex, optionally by the concavo-convex planarization of the surface texture of scum 41.
Be used to form black liquid or the coating of release layer 5, use from above-mentioned delustring China ink liquid or antiglossing pigment removed silica or carbon black and so on as the resin combination after the particle of delustering agent performance function.This is because the adhesion that requires release layer 5 to have simultaneously for delustring layer 4 and scum 41 reaches the release property for transfer printing layer.
The thickness of release layer 5 is 0.1 μ m～30 μ m.When the thickness of release layer 5 was less than 0.1 μ m, the planarization of the surface texture of scum was inadequate, the residual concavo-convex outermost surface that is transferred to transfer printing layer, and the quality in the gloss zone of decorative article reduces.When the thickness of release layer 5 surpassed 30 μ m, even the surface texture of delustring layer all was flattened, and the delustring performance is not enough.Preferably the thickness of release layer 5 is 0.3～20 μ m, more preferably 1～10 μ m.
Fig. 2 means the schematic sectional view as the formation of the transfer sheet of other embodiments of the present invention.On this transfer sheet, further be formed with substrate release layer 6 between substrate 3 and delustring layer 4.The thickness of release layer 5 is strictly controlled, the deficiency so release property likely becomes.For example, under these circumstances, append substrate release layer 6 and get final product, strengthen thus the release property of release sheet 1 relative transfer printing layer 2.
The black liquid that substrate release layer 6 is used while using with formation release layer 5 or the same black liquid or the coating of coating, in order on the face of substrate, to form release layer, method that can be identical by the method with all the time used forms.
In the substrate demoulding China ink liquid that is used to form substrate release layer 6 or substrate mould wash, preferably contain levelling agent.Because the surface of substrate release layer 6 can reduce, the easy wetting expansion of scum, the concavo-convex of its surface texture reduces.
With regard to levelling agent, so long as the material used in the purposes such as Ricinate, surface conditioner, defoamer, rheology control agent just is not particularly limited all the time.As concrete example, can enumerate Tissuemat E, polyester siloxanes, polyether silicone fluorine based polymer etc.
With regard to levelling agent, in substrate demoulding China ink liquid or substrate mould wash, the solid constituent of typically take is benchmark, and its content is 0.01～10 % by weight, preferably 0.05～8 % by weight, more preferably 0.1～6 % by weight.When the content of levelling agent was less than 0.05 % by weight, the fissility of result and release layer was impaired, and when surpassing 8 % by weight, levelling agent manifests on substrate demoulding China ink liquid surface, and result causes the wetability of release layer China ink liquid significantly deteriorated.
Transfer printing layer
Forming the hard conating 7 of transfer printing layer 2, is the outermost layer that becomes transfer printing layer 2 while peeling off stripping film 1 after transfer printing.About hard conating 7, while after transfer printing, peeling off stripping film from decorated article, be configured in the surface of ornament, in order to protect transfer printing layer, have to a certain degree above hardness.
Hard conating 7 forms coating delustring layer 4.As hard conating 7, use while applying heat, ultraviolet ray or electron ray homenergic crosslinked or curing energy crosslinkable resin occurs.As the material of hard conating, can enumerate the ionizing radiation curable resins such as cyanoacrylate system, urethane acrylate, the heat-curing resins such as acrylic acid series, carbamate system, but be not particularly limited.The preferred energy crosslinkable resin is that crosslinked active energy ray crosslinkable resin occurs while applying ultraviolet ray or electron ray.This is because the active energy ray resin can easily be adjusted crosslinking degree by the amount that increases and decreases the energy applied.
As the formation method of hard conating 7, the coating process such as gravure coating method, rolling method, spot printing method, die lip coating process are arranged, the print processes such as woodburytype, silk screen print method.The thickness of hard conating 7 is 1 μ m～50 μ m.If be less than 1 μ m, can not obtain sufficient case hardness, can't maintain the defencive function of article surface.On the other hand, when surpassing 50 μ m, hard conating does not obtain enough transparencies, can damage the decoration functions that dyed layer plays.More preferably the thickness of hard conating 7 is 2～10 μ m.
Hard conating 7 preferably occurs crosslinked after forming.This is because stripping film becomes good from the fissility of delustring layer.Crosslinked degree can be fully crosslinked, in addition, can rest on and obtain MIN partial cross-linked from the good fissility of delustring layer.In the situation that partial cross-linked, hard conating 7 is preferably fully crosslinked after transfer printing.
By following embodiment, illustrate the present invention, but the present invention is not limited to these.It should be noted that, with regard to the amount shown in " part " in embodiment or " % ", just refer to unless otherwise specified weight basis.
